A vehicle height adjustment device includes a rear suspension, an electromagnetic valve control unit, and a weight estimation unit. The rear suspension includes a support member to change a length of a rear wheel-side suspension spring. The electromagnetic valve control unit determines a target movement amount based on an interrelation between the target movement amount and a weight applied to a vehicle, under which the target movement amount is set to an upper limit value when the weight is equal to or larger than a predetermined weight, so as to perform a control so that an actual movement amount of the support member reaches the target movement amount. The electromagnetic valve control unit determines the target movement amount based on a temporary value of the weight. The weight estimation unit increases the temporary value, even when the actual movement amount has reached the target movement amount, when an actual length of the rear suspension does not reach a target length. The electromagnetic valve control unit decreases the target length, even when the temporary value has been increased, when the target movement amount that is set anew and that corresponds to the temporary value that is set anew has reached the upper limit value. The weight estimation unit estimates as the weight the temporary value when the actual length has finally reached the target length.
